Miniature rose plant named ‘POULpar029’

ABSTRACT

A new miniature rose plant which has abundant, red flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrida.

Variety denomination: ‘POULpar029’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety ofminiature pot rose plant which originated from a controlled crossingbetween the female parent ‘KORstoffein’, described and illustrated inU.S. Plant Pat. No. 11,242 dated Feb. 22, 2000, and the male parent, anunnamed seedling. The two parents were crossed and the resulting seedswere planted in a controlled environment. The new variety is named‘POULpar029’.

The new rose may be distinguished from its seed parent. ‘KORstoffein’,by the following combination of characteristics:

-   -   1. ‘KORstoffein’ petals which are Yellow-Orange Group 19D. The        same of ‘POULpar029’ are Red Group 53A.    -   2. ‘KORstoffein’ has a petal count of 25 to 30. ‘PUOLpar029’ has        30 petals.

The new variety may be distinguished from its pollen parent, unnamedseedling created by the same inventors, by the following combination ofcharacteristics:

-   -   1. The parent has a white flower color, whereas ‘POULpar029’ has        a red flower color.    -   2. The parent plant has a petal count of 13 to 15, whereas the        same of ‘POULpar029’ is 30.

The objective of the hybridization of this rose variety for commercialculture was to create a new and distinct variety with unique qualities,such as:

-   -   1. Uniform and abundant flowers;    -   2. Vigorous and compact growth;    -   3. Year-round flowering under glasshouse conditions;    -   4. Suitability for production from softwood cuttings in pots;    -   5. Durable flowers and foliage which make a variety suitable for        distribution in the floral industry.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventors, anddistinguish ‘POULpar029’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and MogensN. Olesen germinated the seeds from the aforementioned hybridization andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark.

‘POULpar029’ was selected by the inventors as a single plant from theprogeny of the hybridization in 2000.

Asexual reproduction of ‘POULpar029’ by cuttings and traditional buddingwas first done by L. Pernille and Mogens N. Olesen in their nursery inFredensborg, Denmark in 2001. This initial and other subsequentpropagations conducted in controlled environments have demonstrated thatthe characteristics of ‘POULpar029’ are true to type and are transmittedfrom one generation to the next.
